*Abstract

Advances inlithium battery technology have spurred substantially growth that has permeatedthroughout the changing energy landscape, becoming ubiquitous systems in portableelectronics and automotive applications. As part of the ongoing effort towards advancing battery performance andstability, researchers at Cornell developed a scalable method for synthesizingtransition metal-carbon nanocomposite anodes and cathodes. This newly developed approach yields across-linked polymer network, which uniformly incorporates nanometer-sizedtransition metal oxide particles that are nearly monodispersed and uniformlyembedded in a porous carbon matrix.

The validation ofthis method is seen through standard electrochemical measurements on lithiumhalf-cells containing a Fe₃O₄–carbon composite anode,which exhibited stable performance at both low and high current output. Inaddition, the method can be readily adapted to synthesize metal oxide/carbonnanocomposites based on different particle chemistries for applications in boththe anode and cathode of LIBs.
